Estimates suggest that annually Americans consume 45 million pounds of caffeine and hot coffee and teas are the most popular sources for the legal psychoactive stimulant drug. Both beverages are associated with having dental health perks as black coffee has been found to lower acid levels on teeth, reducing the odds of cavity development and green tea has been found to be powerful in reducing gum inflammation and subsequently gum disease. Despite the perks of the beverages, when consumed at their steamiest stage, the unflattering side effect may be tooth staining.
Science has shown that heat will cause molecules and atoms to vibrate faster, increase space between atoms and cause expansion. Tooth enamel is one such substance that will expand under heat and during that stage, the tannins in coffee and tea can lodge into the void and as the teeth cool down again, tooth staining can be the result.
Proper oral hygiene can help teeth stay clean and lower the level of dental plaque, and brushing with a whitening toothpaste may help alleviate some of the discoloration. Patients may also choose to get professional teeth whitening from a dentist specializing in cosmetic dentistry.
